Line Cord Information
Question: Why doesn’t my power supply come with the right line cord?
Answer: Some power products use lots of power, far beyond the range of typical electronic products with which we
are familiar. This makes it difficult to identify and provide the correct line cord and plug in all situations. Many
times, higher powered products require the help of a site electrician to provide the appropriate power distribution. In
particular, 3-phase products are typically provided with an unterminated line cord, that is appropriate for the
destination country.
In other cases, the required line voltage and current dictates the line cord that is supplied. For example, the standard
voltage for the 2KW 667xA products is 230 Vac. These products can not be powered off a 120 Vac line because of
the high current required. Another example is the 601xA and 603xA families of autoranging power supplies. While
these can be powered from a 120 Vac circuit, they require currents in excess of 15 A, therefore they are shipped with
a line cord intended for operation on a 30 A 120 Vac circuit.
The Power Products Catalog includes a section on selecting the correct line cord and line voltage for these and
many other situations.
